Abstract: The subject invention relates to the art of adjustable wrenches.  The adjustable wrench of this invention is particularly suited for the gripping of hex head fasteners.  The adjustable wrench has a handle portion and a head portion.  The head portion has two downwardly extending jaws.  One jaw is stationery, the other being moveable.  The moveable jaw moves in an elongated slot which is integral with the head portion.  The moveable jaw and the elongated slot incorporate opposing interlocking surfaces which cooperate in such a manner as to support the moveable jaw during usage.  The moveable jaw is connected to an adjusting means which may be an adjusting screw and an adjusting nut.  The adjusting means controls the fixed relationship between the moveable jaw and the fixed jaw.  In the embodiment which utilizes an adjusting screw its movement and hence the movement of the moveable jaw is controlled by the . rotation of an adjusting nut.  The assembly of the moveable jaw into the head portion may be effected through the aperture which contains the adjusting nut.  The moveable head, adjusting screw and adjusting nut are fully supported in the head portion.  The adjustable wrench of this invention is reversible and may be used in tight quarters.  In the preferred embodiment the jaws of the adjustable wrench have 120 degree angled faces.

Title: Method and apparatus for chemical treatment of subterranean well bores
Inventor: CORONADO MARTIN P
IPC: E21B33/124
Filed: 1990-04-27
Abstract: METHOD AND APPARATUS FOR CHEMICAL TREATMENT          OF SUBTERRANEAN WELL BORES                     ABSTRACT OF THE DISCLOSURE           An apparatus for effecting chemical treatment of any selected portion of a subterranean well bore comprises a pair or vertically spaced, inflatable packing elements which are run into the well on a fluid conduit, such as continuous tubing.   The apparatus permits circulation while being run into the well bore and, when positioned at a desired location, effects the expansion of the two inflatable elements by pressured fluid introduced through the supporting fluid conduit. The applied pressure is trapped within the inflatable elements by axial movement of an inner body assemblage of the apparatus relative to an outer body assemblage, which is opposed by a string.  The relative movement effects the opening of fluid communication between the central fluid conduit and the well bore portion between the inflated packing elements, permitting testing of the sealing effectiveness of the packing elements, and the ap-plication of a treatment fluid.  The same movement, accompanied by an increase in fluid pressure supplied through the fluid supply conduit, effects the opening of a fluid path to the well bore above the uppermost packing element.  The pressurizing and/or testing fluid remaining in the fluid supply conduit may be discharged into the well annulus by supplying pressurized treatment fluid through the supply conduit.  For deflation of the inflatable packing elements, the central body is moved downwardly by the spring, a circulation port is opened and a rupture disc is ruptured through the application of preselected higher fluid pressures, thus permitting drainage of fluid from the inflatable elements and circulation as the tool is withdrawn from the well.

Abstract: ABSTRACT OF THE DISCLOSURE    Calcium formate can be produced with high space-time yields and low engineering expenditure by reacting methyl formate and calcium hydroxide in a molar ratio of substantially 2:1 in an aqueous suspension at 20 to 100°.  At the start of the reaction the weight ratio of calcium hydroxide to water is 1:1 to 1:5.  Prior to or upon distilling off the methanol formed, the crystalline calcium formate is separated from the aqueous phase and dried.  The calcium formate thus produced is better suited as a feed additive than calcium formate obtained as by-product in the production of polyols.
